UNMUNGE(1) MUNGE Uid 'N' Gid Emporium UNMUNGE(1) NAME unmunge - MUNGE credential decoder SYNOPSIS unmunge [OPTION]... DESCRIPTION The unmunge program validates a MUNGE credential (e.g., one created by the munge program). By default, the credential is read from stdin and the metadata and payload are written to stdout. When the metadata and payload are written to the same stream, they are separated by a blank line. OPTIONS -h, --help Display a summary of the command-line options. -L, --license Display license information. -V, --version Display version information. -i, --input path Input the credential from the specified file. -n, --no-output Discard all output, both metadata and payload. -m, --metadata path Output metadata to the specified file. -o, --output path Output the payload to the specified file. -k, --keys string Specify a subset of metadata keys to output. The keys are case-in- sensitive and delimited by whitespace, commas, semicolons, or peri- ods -- as long as the string is treated as a single argument by the shell (e.g., enclosed by quotes). Invalid keys are ignored. If a subset is not specified, all available keys are selected by default. -K, --list-keys Display a list of metadata keys. -N, --numeric Display metadata values numerically. This omits conversions from IP addresses to hostnames, seconds to date and time strings, UIDs to user names, GIDs to group names, and cipher/mac/zip type lookups. -S, --socket path Specify the local socket for connecting with munged. --ignore-ttl Ignore expired, rewound, and replayed errors. --ignore-replay Ignore replayed errors. METADATA KEYS The following metadata keys are supported. STATUS The status of the credential decode operation. ENCODE_HOST The address of the host on which the credential was encoded. ENCODE_TIME The time at which the credential was encoded (according to the local clock of the host that encoded it). DECODE_TIME The time at which the credential was decoded (according to the local clock of the host that decoded it). TTL The time-to-live value (in seconds) placed within the credential. CIPHER The cipher type used to encode the credential. MAC The MAC type used to encode the credential. ZIP The compression type used to encode the credential. UID The user ID of the process that encoded the credential. GID The group ID of the process that encoded the credential. UID_RESTRICTION The user ID restriction placed within the credential. GID_RESTRICTION The group ID restriction placed within the credential. LENGTH The length (in bytes) of the payload. EXIT STATUS The unmunge program returns an exit code corresponding to the return code of munge_decode(). On success, it returns a zero exit code which signifies the credential is valid. On error, it prints an error message to stderr and returns a non-zero exit code. AUTHOR Chris Dunlap <cdunlap@llnl.gov> COPYRIGHT Copyright (C) 2007-2025 Lawrence Livermore National Security, LLC.
